REFRIGERATOR.

' Specification of Letters Patent.

Patented Feb. 9, 1909i Application filed August 30, 1907. SeriaI No. 390,777.

To all whom it may concern.

Be it known that I, AARON C. SAMPLE, a citizen of the United States, residing at Ironton, in the county of Lawrence Vand State of Ohio, have invented new and.` useful Improvements in Refrigerators, .of which the following is a specification. I

This invention relates to refrigerators, and it has for its object to prevent injury to the refrigerator by forcibly dumping or depositing ice in the ice compartment; further objects being to simplify and improve the general construction, and to facilitate the placing of ice in the ice compartment.

With these and other ends in view which will readily appear as the nature of the ing invention.

vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

in the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

ln the drawing, Figure 1 is a vertical sectional view taken through the ice compartment of a refrigerator equipped with the Fig. 2 is a transverse sectional view of the frame structure constituting the invention. Fig. 3 is a horizontal sectional view taken on the plane indicated by the line 3-3 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

1 designates the ice compartmentjof a refrigerator, a portion of the casing` of which is shown at 2, 3 representing the lid or coverand 4 the bottom of the ice vcompartment which has been shown as being provided with the customary lining 5 of sheet metal, such as zinc or other suitable material.

A suitable frame is placed in the ice comg partment, said frame including four corner posts or uprights 6-6 which are connected at their lower ends by sills 7 and at their upper ends by longitudinal cap pieces 8 and transverse cap pieces 9 g it being understood, however, that the construction of the frame may be varied at will, and that the said frame may be built into -the refrigerator structure. The corner posts are- 4provided with grooves 10 wherein are guided cross pieces 11 which are vertically movable and adjustable by means of screws 12, the upper and lower ends of which are journaled respectively in bearings 13 and 14 xed upon the transverse cap pieces 9 and upon the end sills 7. The screws 12 are provided near their lower `ends with bevel pinions 15 meshing with bevel pinions 16 upon a shaft 17 supported for rotation in the bearing members 14 u'pon the end sills 7; said shaft is in axial alinement with an aperture, 17 formed in the refrigerator casing, and through which may be inserted a crank 18 whereby said shaft may be conveniently rotated for the purpose of rotating the screws 12 thus causing the cross pieces 11 to travel upward or downward according to the direction of rotation. The aperture 17, when the crank 18 is not in use, may be covered by a pivoted flap 18. The two screws 12-12 have been shown as being respectively right and left threaded, and the gearing is so arranged as to cause the said screws to be simultaneously rotated in opposite directions within the scope of the invention it is, however, evident that the screws may be similarly threaded, in which event the gearing will be arranged to rotate both screws in one direction. The ice pan 19 which is supported upon the vertically movable cross pieces 11 may be provided with apertures 20 for the passage of the screws.

lt will be readily seen that by rotating the shaft 17, the screws 12 may be rotated to cause the cross pieces carrying the ice pan to move in an u ward direction, thus enabling ice to be rea ily placed in position thereon, without bruising or injuring the refrigerator or its lining after the ice has been placed in position, the pan may be lowered until the ends of the cross pieces 11 are supported at the lower ends of the guide slots 10, thus relieving the screws from unnecessary strain.

This invention is extremely simple, and serviceable for the purposes set forth. It may be readily applied to refrigerators of ordinary make; or refrigerators may be specially constructed to embody the features of the invention.

Having thus fully described the invention, what is claimed as new is A refrigerator comprising a casing having an ice compartment and an opening in one of its walls communicating with the base portion of said compartment, a frame within said compartment embodying` front and rear sets of corner standards and interconnecting top and bottoni longitudinal and transverse bars, said standards being` iiorined with grooved guideways, screw shafts disposed between the respective sets of standards and journaled in the top and bottoni eross-bars, said shafts being provided at their lower ends with pinions, transverse earrier bars having their end portions slidable in the grooved guideways in the standards, saidbars being` provided with intermediate threaded openings engaging the serew shafts, a tray disposed within the fraine and perfon rated for the passage of the screw shafts, said traT resting at its ends upon said supporting bars and adapted to be elevated and lowered thereby upon the revolution of thel serews in one direetion or the other, a shalt journaled in the lower front and rear crossn bars of the frame and earrying gears meshing' with said pinions, one end of said shaft being arranged in line with said opening; in the easing7 ,vherebT said shaft is adapted to he engaged by an operatingl erank or the like inserted through said opening7 and a cover for elosingj)` the opening when the crank is withdrawn.

In testimony whereof l aix in)v sigjnahn'e in presenee of two witnesses.
